The function of the Sinter Plant is to supply the blast furnaces with sinter, a combination of blended ores, fluxes and coke which is partially ''cooked'' or sintered. In this form, the materials combine efficiently in the blast furnace and allow for more consistent and controllable iron manufacture.

Blast Furnace Ironmaking an overview ScienceDirect Topics
Jan 01, 2010 · Fuel efficiency is defined as the utilization percentage of reducing gas For example, blast furnace ironmaking including sintering and coking plants consumes about 6575% of the entire energy at an integrated steelworks (ca. 11–12 GJ/t hot metal) (Babich, 2009). Both direct and indirect coal use, e.g. in the form of coke, is presented.
For Integrated steelmaking, the primary sources of GHG emissions are blast furnace stoves (43 percent), miscellaneous combustion sources burning natural gas and process gases (30 percent), other process units (15 percent), and indirect emissions from electricity usage (12 percent). For EAF steelmaking, the primary
become the widely accepted and preferred Blast Furnace burden material. Presently more than 70% of hot metal in the world is produced through the sinter. In India, approximately 50% of hot metal is produced using sinter feed in Blast Furnaces. Large sinter strands 6 m wide and with a sintering
Influence of high grade iron ore usage on the performance
of using high grade ore to the performance of Sintering and Blast Furnace processes in terms of energy savings, CO 2 emissions, and logistic benefits to the mills in the region. Keywords: high grade iron ore, sinter, blast furnace, Brazilian fines, pot sinter, Alumina * Msc. Metallurgical Engineer R&D Technical marketing – Vale S.A. Brasil
The purpose of the sinter plant is to process fine grained raw materials into a coarse grained iron ore sinter, ready to be charged to the blast furnace. Sintering of fine particles into a porous clinker – sinter – is necessary to improve the permeability of the burden, making reduction easier. A high quality sinter has high reducability, which reduces the intensity of blast furnace

HOW A BLAST FURNACE WORKS Introduction The purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom.
Blast Furnace Operation an overview ScienceDirect Topics
In a blast furnace, iron ore reacts with hot coke to produce pig iron. The sintering or pelletising process prior to the blast furnace operation is added to allow blending of iron ores and also to control the size of the blast furnace feed. Sintering or pelletising improves the blast furnace operation and reduces energy consumption.

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace.The final product, a sinter, is a small, irregular nodule of iron mixed with small amounts of other minerals. The process, called sintering, causes the constituent materials to fuse to make a single porous mass with little change in the chemical
Characterisation of the Physical and Metallurgical
The blast furnace is still the dominant form of iron production, but over the years, direct reduction methods have increased due to a number of reasons. Overall, iron production methods have optimal requirements with respect to the feed materials especially iron ore. In this study, tests were carried out on Muko iron ore from Uganda to analyse its suitability to meet the feed requirements of
Numerical analysis on blast furnace performance with novel feed . Thus charging CCB enhances the rates of reduction and carburization and lowers operation temperature of blast furnace. Less sinter and coke feeds decrease energy consumption in sintering and coking processes.
component in the blastfurnace burden, the production of highquality sinter is crucial for assuring of offgas in your sinter plant by up to 50 percent. This significantly lowers not only environmental pollution but fine ores/pellet feed, additives, dusts, solid fuels, return
Effect of Sinter Mix Composition and Additives on the
Increasing amounts of roll scale, ore fines, return fines, and blast furnace slag were most beneficial to feed permeability, sinter bulk density, and strength. Burnt lime additions improved feed permeability but were not beneficial to sinter strength or bulk density. Sinter
EFFECT OF MAGNETITE, HEMATITE AND PELLET SCREENINGS
increase in the usage of pellet in the blast furnace burden. Others have chosen to keep sinter amount constant and instead tried to improve the quality of produced sinter by various means. Keeping quality has in most cases meant that fine ores as concentrate or even pellet feed has been added to the sinter
If above expected quality sinter will be replaced with iron ore in blast furnace, maximum ratio (80 85 %) of sinter can be used safely. Production cost of the sinter has to be considered while using the sinter in blast furnace which is depending on the cost of raw materials for sinter making.
